On Ascochyta Blight from Dr. M. Draper, SDSU, Associate Professor and Extension Plant Pathologist
My recommendations for managing this disease are:
1) Rotate away from chickpeas 3 out of four years,
2) Buy the best seed lot possible with the lowest level of Ascochyta contamination,
3)Treat the seed with LSP seed treatment,
4) Plant to treat with Bravo at the first sign of disease,
5) Treat with Quadris/Headline (assuming the labels are approved) 10-14 days later if cool wet conditions persist,
6) If a third treatment is needed, use Bravo again.
This is a worst case solution. Most growers will not consider three fungicide applications. If only one treatment is used, Quadris/Headline could be that treatment, butDO NOT follow that treatment with a secondapplication of the same product.
